EMPTY CANS ARE EXTREMELY FRAGILE AND PRONE TO DEFORMATION. In the one-way conveyors before infeeding the Filler Machine, they reach speed < 5 m/s. Interposed along their journey from the Depalletiser til the Filler a twist, like the one visible here, one more source for deformations and jams (image credit Rexam®).
Visual check of empty cans just after having been depalletised let the human being front the impossible mission to filter defective cans before they reach the following Canning Line Machines.
Why ?
Because a single deformed Can may:
- easily jams the Twist before the Filler,
- ‘escapes' by the Filling Valve,
- jams the Seamer.
Many of these cases terminate in long forced stops of the entire Canning Line, with several stretched cans lying in the Seamer. After adding all other possible types of Cans' defects, like those preventing its sale ability, e.g. defective print or scratches, it becomes evident this task can only be accomplished by a device emulating some of the human being high level cognitive functions: an Electronic Inspector.

WHAT VENDOR OFFERS THE WORLDWIDE BEST SYSTEM TO ADJUST INSPECTIONS’ SENSITIVITY ? PRESSCO. Its RETRO-SPEC™ technology assures the easiest thinkable sensitivity adjustment. A huge amount of the last processed containers, PET caps of preforms is kept in memory, including all those considered defective and rejected. To readjust sensitivity is made banal by mean of a slider control showing immediately what container before considered “defective” should later be considered “good” containers. RETRO-SPEC™ (retrospective) philosophy allows an immediate insight to the consequences of each one sensitivity readjustment. The image above. shot by our staff in an empty can inspector is available to all different models of PRESSCO®
